Musnad Ahmad Hadith 23771

It is narrated from Utban bin Malik (may Allah be pleased with him) that once I presented myself before the Holy Prophet (ﷺ) and said, "O Messenger of Allah! A flood comes between my tribe's mosque and me. If you could come sometime and pray in my house, I would select that place as my prayer area." The Holy Prophet (ﷺ) promised to do so. So, one day, the Holy Prophet (ﷺ) came with Abu Bakr (may Allah be pleased with him), entered the house, and said, "Which place do you want to make your prayer area?" I pointed to a corner of the house. The Holy Prophet (ﷺ) stood up, and we formed rows behind him. The Holy Prophet (ﷺ) led us in two rak'ahs of prayer. We invited the Holy Prophet (ﷺ) to stay for a meal. When the Ansar heard about this, they began to come to see the Holy Prophet (ﷺ), and the whole house filled up. One man said, "Where is Malik bin Dukhshum?" Another replied, "He is a hypocrite." The Holy Prophet (ﷺ) said, "Do not say that. He recites 'La ilaha illallah' for the sake of Allah's pleasure." The man said, "But we see that his attention and conversation are inclined towards the hypocrites." The Holy Prophet (ﷺ) repeated the same sentence. Another man said, "Why not, O Messenger of Allah!" Upon this, the Holy Prophet (ﷺ) said, "Whoever comes on the Day of Judgment bearing witness that there is no god but Allah, seeking Allah's pleasure, Allah has made the fire of Hell forbidden for him."
